The compact WTC3243 temperature controller module achieves 0.0009°C temperature stability. Its award winning package can be integrated with a heatsink, thermal washer and fans for easy prototyping, especially when used with the dedicated evaluation PCB.

Additional information

The linear, PI control loop offers maximum stability while the bipolar current source has been designed for high efficiency. Driving up to 2.2 A for, either TECs or Resistive Heaters, the WTC3243 is easily configured for any design. Virtually any type of temperature sensor can be used and a built in sensor bias current source simplifies use with resistive temperature sensors. Set by external resistors, the Proportional Gain and Integrator Time Constant can be modified to optimise temperature overshoot and stability.

Use the WTC3243HB with Li-ion batteries.
